About Penteo

Established in 2012, thousands of post-production mixers, sound designers, composers and educators in over 50 countries rely on Penteo audio plugins to deliver an immediate, phaseless, high quality upmix or downmix from any format between stereo to surround up to 16-channel immersive sound formats.

We focus on being the first to bring the latest sound and technology innovations to our customers so that they can benefit the most. Penteo has led the market being the first phaseless upmixer, the first to port to 64 bit architecture and the first integrated 16 channel upmix/downmixer.

We are proud to have won multiple industry awards including twice being named 'Upmixer of the Year', and won ProTools Expert’s head to head ‘Upmixer Shootout’ competition.

PerfectSurround technology delivers a perfect stereo upmix that will always downmix back to the original stereo 100% ITU, every time from any source.

Only PerfectSurround technology is completely phaseless so mixers never have to compromise their upmix to get an ‘exact’ downmix: PerfectSurround delivers both every time from any source file.

PerfectSurround results in a deeply immersive and most natural sounding upmix with wide channel separation of the highest quality without introducing any unwanted sonic artifacts into the process.

We have invested in the best, most unique technology so that our controls and logic do the heavy work to speed your surround or immersive upmix session.
